Purpose: To describe the short-term complications associated with intravitreal triamcinolone acetonide (IVTA) injection in the treatment of posterior segment disorders.
Methods: The medical records of 784 patients (929 consecutive eyes) were retrospectively reviewed at a single institution. One or more IVTA injections for treatment of a variety of steroid-responsive posterior segment disorders (predominantly diabetic macular edema, choroidal neovascularization, and retinal venous occlusions) were administered. Adverse events occurring within 3 months of the initial injection were identified.
Results: The most common adverse event occurring within 3 months after the initial injection was steroid-related ocular hypertension, with intraocular pressure spikes of >21 mm Hg in 21% of eyes and >25 mm Hg in 11% of eyes. Ocular inflammation occurred in six eyes (0.6%): four eyes with sterile hypopyon and two eyes without hypopyon. Three eyes (0.3%) had corneal epithelial defects thought to be related to pretreatment with povidone-iodine solution. No eyes had culture-positive infectious endophthalmitis. Cataract progression was not assessed in this analysis.
Conclusion: IVTA injection for the treatment of steroid-responsive disorders of the posterior segment, when administered under sterile conditions, is associated with a low incidence of serious vision-threatening adverse events within the first 3 months after injection.

Background: Evaluating the correlation between degenerative meniscus tears and medial meniscus extrusion is necessary to determine the appropriate treatment plan for early-stage knee osteoarthritis. This study evaluated the relationship between degenerative meniscal tears and medial meniscus extrusion in early-stage knee osteoarthritis by using ultrasonography.
Methods: A total of 132 knees from 123 patients with early-stage knee osteoarthritis were evaluated retrospectively.
TEER for SAM of the Mitral Valve and Flail Posterior Mitral Leaflet: 1-Clip Solution.

Transcatheter edge-to-edge repair (TEER) is approved for patients with symptomatic severe mitral regurgitation (MR) who are deemed inoperable or at high surgical risk with life expectancy of more than 1 year, but has also been used off-label in patients with hypertrophic obstructive cardiomyopathy (HOCM) for symptomatic relief who are not candidates for septal reduction therapy. An 83-year-old woman with decompensated heart failure was found to have HOCM with systolic anterior motion of the mitral valve and a large P2 flail segment with ruptured cords. TEER was performed resulting in mild MR and resolution of the prior left ventricular outflow tract gradient.

Background: Severe neonatal inflammatory conditions in very preterm infants (VPT: <32 weeks gestational age, GA) are linked to adverse neurodevelopmental outcomes. Differences in white matter (WM) microstructure of the corpus callosum (CC) have been observed at age 6 in VPT children with a history of severe neonatal inflammation. The goal of this study was to determine whether these CC differences can be detected at term-equivalent age using diffusion MRI (dMRI), and whether neonatal inflammation is associated with altered WM in additional tracts implicated in the encephalopathy of prematurity.

The pathogenesis of type I Chiari malformation (CIM) is complex and remains unclear. The theory of posterior cranial fossa incompatibility has gained widespread acceptance in recent years. In the patients with CIM combined with syringomyelia, scoliosis is a common occurrence, with severe cases often leading to complications that necessitate surgical intervention.

Background: Acute bronchiolitis (AB) is the most common lower respiratory tract infection in infants. Clinician diagnosis and management vary due to limited objective assessment tools. Point-of-care lung ultrasound (LUS) offers a promising diagnostic and prognostic tool in the emergency department (ED), however, the time to perform LUS is of concern in the emergency setting.
